Smartphone microphone BOYA BY-MM1+

The BOYA BY-MM1+ is a compact cardioid microphone designed to improve the sound quality of videos compared with built-in microphones. It features a wired 3.5 mm interface and is supplied with both TRS and TRRS cables, making it compatible with smartphones, cameras, camcorders, audio recorders, and PCs. The microphone has a sensitivity of -42 dB, a frequency response of 35–18000 Hz and a signal-to-noise ratio of 76 dB. Its aluminium housing is lightweight and compact (81 × 22 × 86 mm), providing a portable solution for on-the-go recording.

Advantages

The BOYA BY-MM1+ delivers clearer directional audio through its cardioid pickup pattern, reducing ambient noise compared with built-in microphones. Its plug-and-play wired connection requires no battery, and the included TRS and TRRS cables expand compatibility across a wide range of devices. The supplied anti-shock mount reduces vibration, cable and handling noise, while the metal construction keeps the unit lightweight and durable.

How to use

Connect the appropriate cable (TRS for cameras/recorders or TRRS for smartphones) to the microphone and plug the 3.5 mm jack into the device's mic input. Mount the microphone on the camera hot shoe or use a suitable adapter, and attach the anti-shock mount to minimise handling noise. Point the microphone toward the subject to take advantage of the cardioid pattern, and check input levels in your device to avoid clipping. No battery is required; the microphone draws power through the connected device where applicable.

Recommendations

For best results, position the microphone within 30–60 cm of the speaker and avoid placing it near strong wind or noisy surfaces. Use a foam windshield or external windscreen when recording outdoors to reduce wind noise.
